Filed Sept. 14, 1928 Patented Apr. 22, 1930 UNITED STATES LEON IBItlNOIJ?,` OF CHICAGO, ILLINOIS EGG- CARTON i Application led September 14, 1928. Serial No. 305,911.

This invention relates to cartons for eggs and like commodities. It is advantageous 1n the respects that'the-carton is reinforced adequately from end to end, it provides a cushion support for the eggs or ot-her contents, and it is ventilated clear through so as to preserve the carton contents in proper condition. The present carton which is characterized by features such as these is, moreover, simple loand inexpensive to produce and set up. By

way of exemplification of this invention, reference is made to the accompanying drawing whereinv l Figure 1 shows in perspective my carton with the front wall partly broken away to expose more of the' inte-rior thereof;4

Fig. 2 is a transverse section through th carton taken anywhere intermediately of its ends; and

Fig. 3 is an elevation of a carton having 7:.. slightly modified construction.

The present carton is desirably formed of a suitable `card board blanked out to the shape required for providing, when bent up into serviceable position, a front wall 4 joined along its lower edge to a bot-tom 5 which in turn is joined to the lower' edge of a rear wall `6 which supports at its upper edge, a cover 7 the free edge of which is provided. 30 with ua depending flap 8. 'The carton ends comprise in each instance a. rectangular in- .ner wall 9 constituting a bent-up extension of the bottom 5, and a pair of tongues l() which are extended from the front and rear walls to occupy positions along the outer face of the inner wall 9. These tongues, as will be noted from the drawing, present upper edges in mutual alignment with the corresponding edge of the associated wall 9, and although they extend toward each other, they remain separated in the center region of the carton end. ',Each tongue is in the general form of a truncated right angle triangle with the base vertically disposed along the carton corner, the side which is perpendicular thereto being the top edge of the tongue. The remaining side a of the triangle proceeds upwardly and inwardly from the lower end of the base, preferably at an angle of about 45, and stops `short at its juncture with the line of truncation which is formed by the vertical edge b.

Means -are provided for securing the tongues so provided to the associated end wall 9, and for this purpose stitching or stapling 11 may be resorted to for such interconnection. The end components, when so joined,A serve to maintain the carton in a set-up condition ready for use. As it is desirable, however, to collapse the carton for packing, shipping, or storage purposes, I provide in each end wall 9 a bend line e coincident with the edge a of the tongues which extend from the rear wall 6, and in the front wall 4 I provide two other bend lines d each extending from itsl lower corners thereof at angles of approximately 45. l noted may conveniently be provided by scoring the material of which the carton is made. When so constructed the entire carton may be folded down with the front wall disposed adjacent the bottom, the ends over the front wall, and the cover over the ends.

Within the carton is arranged a 'filler which, by preference, provides individual cells or pockets for the reception of the eggs or other commodities. A fille;` which is particularly suited for the purposes vof this inveiition is suggested in Figure 2 wherein I have illustrated a central partition 12 extending longitudinally of the carton to interlock with a series ocross walls 14 with which are interlocked other outer partitions 15 having a swinging mounting by which they may. turn from nearly horizontal positions, as shown, to positions which are vertical. When swung to this latter position the filler may be collapsed in its entirety. In each of the cross walls is formed a pair of segmental slots 16 through which are extended body portions 17 of-the outer partitions, these slotted openings under all conditions, however, being of appreciable area. Cooperating with these openings to promote ventilation through. the carton are windows 18 in the end walls 9, these windows being located between the tongues 10, and having desirably a triangular form so as not tobe overlapped thereby. The eggs or other contents are receivable in two rows on opposite sides of the central Bend lines of the kind partition 12, where they may rest upon the outer partitions of the carton bottom. I may find it desirable to reinforce the carton in a longitudinal direction and for this purpose utilize, by preference, a plurality of longitudinal corrugations 19 which, as shown, are in two series, one centrally of each row of cells. These corrugations, which are formed in the material of which the carton is composed, may extend for the length thereof, and also vertically of the end walls 9, if desired. Should the carton be equipped with a filler having no bottom support for the eggs, then the latter will be rested directly upon the corrugations which aiford thereto a degree of protection somewhat greater than would the flat bottom of the carton.

Referring now to Figure 3, l have illustrated a modification in the carton end wall. In this instance the end Wall 20 extends upwardly only as far as the juncture of the edges w and b so that thereabove and between the two tongues 10 there is an intervening open space constituting a ventilating window. ln this construction, as in the other, the tongues are joined to the end wall as by stitching or stapling 11, and in all other .respects as well there may be exact similarity.

A carton produced in accordance with my invention is simple, inexpensive, and readily set up for use. It may receive a paraiin treatment by which the material whereof it is made is rendered impervious to moisture and non-absorptive of odors, etc. Manifestly, in various respects it may may be changed or altered, and in so far as any such modifications fall within the purview of the ap- 13eme-se vided with transversely spaced groups of longitudinally extending corrugations for reinforcing the carton.
